got a question for my code.

[akim3]

I have a code that calculates the number of days between dates. It considers leap years and different days among months. The problem I have is when i debug the code nothing comes out.

Here is the code.
#include<iostream>
#include<fstream>
using namespace std;

bool wheep();
int daysinmonth();

bool wheep(int yr)
{
if (yr % 400 == 0)
return true;
else if (yr % 4 == 0 && yr % 100 != 0)
return true;
else
return false;
}
int daysinmonth(int m, int y)
{
switch (m)
{
case 1:
return 31;
case 3:
return 31;
case 5:
return 31;
case 7:
return 31;
case 8:
return 31;
case 10:
return 31;
case 12:
return 31;
case 4:
return 30;
case 6:
return 30;
case 9:
return 30;
case 11:
return 30;
case 2:
{
if (wheep(y))
return 29;
else
return 28;
}
default:
cout << "error";
}
}
int main()
{
int m1, d1, y1, m2, d2, y2, total;
ifstream fin("dates.txt");
fin >> m1 >> d1 >> y1 >> m2 >> d2 >> y2;
if (m1 == m2 && y1 == y2)
total = d2 - d1 + 1;
else
{
total = daysinmonth(m1,y1) - d1 + 1;
for (int i = m1 + 1; i < m2; ++i)
total += daysinmonth(i, y1);
total += d2;
}

while (!fin.eof())
{
cout << m1 <<" "<< d1 <<" "<< y1 <<" "<< m2 <<" "<< d2 <<" "<< y2 <<" "<<total<<endl;
fin >> m1 >> d1 >> y1 >> m2 >> d2 >> y2;
}
fin.close();

system("pause");
return 0;
}
this is the file its reading
1 7 9 1 10 9

Perhaps, the fin already reached the end-of-file?

BTW, why do you write this code rather than use CRT date/time functions?

when i debug the code nothing comes out

You need to work on your debugging skills. Put a breakpoint before the section that prints stuff and find out why this code never is reached by your program.

... and please use code tags when posting code. The code as displayed is very unreadable. Go Advanced, select the code and click '#'.

As Victor said in post #2, with the input file containing just 1 one line by the time the code comes to the while loop, fin is at the eof so the code within the while loop doesn't get executed so nothing gets printed.
